X2 and Y2 not responding

I am building a Primo using a SKR pro v1.2 board with a touch screen
I hooked the power, touch screen, the steppers and small fans to function test.

Stepper X1 Y1 and Z1 as well as Fan0 all work and respond to touch screen commands
X2 and Y2 not responding nor is fan1 or fan2

What steps should i take to Trouble shot this?

Have you loaded the dual firmware files onto the boards yet?

no. I will attempt that… and see what happens…
thank you for the quick suggestion…

I attempted to load the dual firmware and i got the green light to flash but now none of the stepper work
I am not sure if I was getting the sequence right, on the web instructions it says
“Make sure to unplug both grey exp½ cables for the screen before proceeding. Insert the MicroSD back into the control board, reset, and the board will flash a few green LED’s for a second or two”
I turned off the power to the board and unplugged the 2 grey ribbon wires, at this point I am not sure if I power up before or after inserting the MicroSD. nor am I sure if I only have to push the controller ‘reset’ or the Touch screen reset or both. I have tried both processes with what appears to be the same result but as I stated on the last attempt I did get the green lights flashing but still ALL steppers are inactive.

this is what is no my micro

That is the tft firmware, not the skr firmware.

The firmware.cur might have been the skr firmware at one point.
